Following are simple steps to get everything started:

1) Build MySQL server. Please note libevent 1.4.12 is linked statically into daemon memcached.

2) Start MySQL server. (make sure libmemcached.so and innodb_engine.so are copied to MySQL plugin directory).

3) Create the configure table and a demo table by running innodb_memcached_config.sql

mysql < scripts/innodb_memcached_config.sql

4) Install the memcached daemon plugin:

mysql> install plugin daemon_memcached soname "libmemcached.so";

5) Test it out
telnet 127.0.0.1 11211

set a11 0 0 9
123456789
STORED
get a11
VALUE a11 0 9
123456789
END

6) Run memcapable
Memcapable is part of libmemcached package, it is available at "https://code.launchpad.net/~libmemcached-developers/libmemcached/trunk". If you did not install libevent by yourself, you might need to set LD_LIBRARY_PATH to point libevent.so in the libevent directory.

All tests passed

7) memcached command line options now can be set by specifying MySQL configure variable "daemon_memcached-option"

8) You can also configure the commit batch size by specifying boot time system variable "daemon_memcached-w_batch_size" and "daemon_memcached-r_batch_size" (--loose-daemon_memcached-w_batch_size=100).

9) To enable binlog, please turn on server configure variable
"innodb_direct_access_enable_binlog" along with "log-bin" at server boot time:
msqld ... --log-bin --innodb_direct_access_enable_binlog=1
